If there is only high speed fan, then replace the resistor assembly in the heater plenum. If there is no fan at all, then check the ground to the blower- the wire fails down in the fender well. Just run a new ground from a convenient spot to the motor's plug harness. Or it could just be a bad blower motor.

Blower not working on a 1994 Cadillac

Go under the hood and test the positive wire that goes into the blower motor, it is a single wire with a sort of insuklated plug connector that locks onto a spade contact, check with a 12v test light if voltage replace the blower motor..very common, should be approx. 6 small 5/16 or 1/4 " bolts holding it in around its flange up against the fire wall on the passenger side top.

Humming noise coming from my 1994 cadillac deville especially during the hotter months

Late model Cadillac Deville's and Seville's may experience a humming noise in the passenger compartment when the heater is on high and the blower is set on a medium to high speed.

GM has determined that the most likely cause of the humming noise is from the positioning of the blower motor within the HVAC housing, causing a restriction of the incoming airflow. (GM TSB 03-01-37-001)

The recommended repair for this symptom is to reposition the blower motor.

1. Remove the right side sound insulator.
2. Loosen the three blower motor retainer bolts. (Do not remove bolts)
3. Shift motor as far as allowed toward the vent tube.
4. Re-tighten the retainer bolts.
5. Re-install right side sound insulator.

Hi i have a94 deville and the blower stopped working and a funny smell (like something is burning in dash)What could cause this?

It may be blower motor failure,I would suggest you replace the blower motor and also replace the blower resistor.The motor is located under the passenger side of the dash,Remove the plastic cover to access it.The resistor is located on the same side also.

I'm having a problem with my 95 cadillac deville! it seems to be loseing power from the battery after a full charge. any suggestions?

you need to have the battery load tested first,then charge or replace it,then check voltage at battery with a multi meter,start car,turn on high beams,blower motor,and four ways,and pull down in gear and have a friend check voltage at battery again,it should be over 12.50 volts anything lower replace alternator.

Heater fan doesn,t work

if you are getting power at the fan plug, it is possible that the recycled motor is bad.
